It has been proven through multiple studies that physical fitness and physical education class in grade schools do have some type of positive impact on a child's academic performance. Students who were involved in at least five hours of physical education a week had a higher academic performance compared to students who were only involved in 40 minutes a week. The students with more PE time also received higher scores in math on standardized tests, even though their math class was cut short. There was also a study done based on the type of instructors for the P.E. There were professional and trained. The classes taught by the professional were given more time than the others and only showed an improvement in fitness along with a small decline in academic performance. The amount of time spent in P.E compared to class really didn't show much difference in the academic performance but it was proven that children who are active during school have higher GPAs. Physical education in school has a powerful effect on children when it comes to class behavior, self esteem, self image and socially which are qualities that make a child want to be more involved with learning because they feel more confident as a whole.

Can exercising have damaging effects on your heart? If so, can you prevent it?
Renee Neltner
As it turns out, there is a chance that exercising can damage your heart. Although this is pretty rare, there are circumstances where exercise can have damaging effects.
Where "routine exercise is highly effective for prevention and treatment of many common chronic diseases and improves cardiovascular (CV) health and longevity", excessive exercise or over training "may induce pathologic structural remodeling of the heart and large arteries".
Since this kind of heart condition is brought on by partaking in over training, it is possible to prevent it. Make sure that while you are training your body, you give it enough time to rest and repair any damages before you get back up and go at it again. Allowing your body to recuperate after you exercise is just as important as the exercise itself.

What are the negative risk factors of exercise?
Our class discussion about the video of the professor talking about how regular exercise isn't always the healthiest choice got me thinking about the risk factors that exercise can cause. Majority of individuals know that exercise causes stress on the body or joints especially when doing intense exercises. Yet I found that if someone is poorly trained, dehydrated, already stressed with prior injuries, or under recovered many capabilities can become problematic such as serious injury to the body or hospitalization from dehydration. Also I found that while increasing the amount of exercise one does there is a increase in cardiac complication such as a heart attack or heart rhythm disorder yet this is a very low chance. To lower the chances of this happening one should be properly trained as well as know their own risk factors. For example older individuals are at higher risk and anyone who has been diagnosed with any cardiac condition, diabetes, high blood pressure etc. should consult a physician before intense exercise. Overall from all the research I did majority of the time exercise greatly benefits the body but everything comes with risk factors and it all depends on other factors such as age, current health, training status as well as many other factors.

Is a low level of fitness associated with a shorter life span?
Ellen Rehm
Based on research conducted at the Institute for Aerobics Research in Dallas, Texas, more than 13,000 healthy men and women were given examinations and tests in order to assess their fitness levels. The first test was a preventive medical examination and the next was a maximal treadmill exercise stress test. When the individuals were tested, no one displayed any sign of cancer or heart disease. This study lasted 8 years, and 240 men and 43 women died. The results of the study revealed interesting statistics. The lower the death rate from cancer and heart attacks, the higher an individuals initial fitness level is. High fitness athletes were not at any lower risk of death versus people with average fitness levels. Findings proved that there was a good improvement among individuals fitness which provided them health benefits. If people simply walked 30 minutes a day, their mortality rate would decrease. The main factor the researchers stressed in the study was that health benefits of physical activity can be achieved at moderate levels of exercise.
I found this study interesting because a lot of people believe you will live longer if you exercise at high levels of fitness. This study proves that moderate levels of fitness will suffice your health benefits. Fitness only benefits people with longer healthier lives.

Get a plan and stick to it
Anysha
Many people can start off
exercising regularly and even began to incorporate healthy nutritious foods in
their diet, but why cant people seem to stick to their plan? People seem to
have a problem with repetitive actions. Waking up and going to the gym 5 days a
week and seeing the same people there could become quite boring for certain
individuals. For some beginners exercising is no fun. The pain of exercising
seems to outweigh the joy. When you come home from the gym and cant seem to
walk up the stairs without pain could be a downer for people. Another problem with exercising is that people expect fast results. They think that if
they worked out for one week then they should see a huge difference with their
body. You can’t expect to drop 10 pounds and 2 pants sizes after just one hard
week in the gym. According to fitnessblender.com a person loses an average of a
1-2 pounds a week while exercising.
Some ways that could help people
stick to their plan is to have a gym buddy. This is someone who will help push
you to get off the couch and go workout together. Making an exercise plan and
sticking to it all starts with your MIND. You must be consistent and illustrate
dedication to exercising in order to receive the results in which you set out
to do. However, you must posses patience. Patience is the key!
Do not expect fast results with very little consistency and dedication. Hard work pays off.

When people think of stress they have a negative attitude and cannot think of any positive outcomes in their lives. However, recent research has proven that small doses of stress can benefit the brain and the body. If stress is not allowed to linger, it can effectively provide a burst of energy to an individual, allowing a person to be more efficient when completing his or her task. As a result, an individual may feel more in control of his or her life and maintain a sense of accomplishment.
In addition to making us more productive, stress can improve the activity of brain cells. This is especially important in helping to combat certain diseases like Alzheimer’s. Furthermore, stress can help protect the body by possibly preventing certain cancers. Stress is able to boost the immune system and enhance anti-tumor activity. In fact, stress has proven to help protect against breast cancer because it surprises the production of estrogen. Lastly, other research indicates that heart function is improved which can benefit the entire wellbeing of a person.

Exercising benefits your health in many ways but to what extent does it start to hurt your body?
Danielle Tudor
Exercise has many positive effects on the body and should be made a routine to stay healthy. However, too much exercise can turn into a bad thing especially for the heart. Overworking the body can put a strain on the heart and ultimately cause scarring and plaque buildup. Studies have shown that a little exercise is good for the body and you no longer need to spend hours in the gym.
Exercise relieves stress but when overexerting your body it can start to cause stress. To prevent exercising too much you should never repeat the same body part two days in a row. The body needs time to rest and rejuvenate itself. Some signs to knowing that you are overexerting your body are that you are tired when you leave the gym and are ready to take a nap. Being sore for more than two days means that you worked your body too hard and should ease up on your next workout. If your heart rate is elevated when you are at rest you need to decrease the intensity and length of your workouts.
